Manufacturing environments can be very challenging for wifi based devices. Below is a (non-exhaustive) list of things that can cause problems with wifi signals. If the problem persists and dropping an Ethernet cable to the device is an option, please contact a Caddis sales representative to ask about swapping out your wifi based device for an Ethernet based one.
- Moisture absorbs radio signals at the frequencies that wifi operates in. Excessive moisture or wet materials in an environment can decrease wifi signal range.
- Concrete between the device and a wireless access point. Concrete holds moisture, which absorbs the radio signal's power in some cases.
- Metal between the device and a wireless access point, and excessive metal in the environment (i.e. the building is a metal building with metal walls).
- Electrical interference from other radio equipment, or equipment such as EDMs, hydraulic pumps, high voltage contactors, etc
